That sure sounds like a human knock on the door. A living human knock and the lady hurries to unlock the door and open it. It takes like half the time it did her last go.

You drop her home baked cookie you wear nervously chewing on to the ground and look at the Man coming inside. A Mean looking Man with permed spiky hair and a chubby angry posture.
